xbox was connected to the computer? or was it connected to your router? the xbox is saying it didn't get an IP address, so it apparently has no connection with the server that assigns IP Addresses... like your router, or whatever such device you have. your DHCP server doesn't tend to be a computer.

Maybe you should try marking this thread as solved. Today i went to a lot of thread that is not marked solved but when i went inside the poster told me it is already solved. Marks this thread as solved so it won't confuse other people.
